sired to supplement the action of the spring in returning the sleeve to normal position, and for this purpose additional springs may be used for seating the sleeve as indicated in Figs. 6 and 7; as shown in said figures a supplemental spring 8 is interposed between the top of the sleeve yoke l1 and an arch bar 7b attached to studs 7a so that when the sleeve is raised both springs 4 and 8 will be tensioned and the sleeve will be returned to normal position, and held in normal position with greater pressure, than the puppet valve is held to its seat.

The outlet valve B is arranged beside `valve A and is constructed like valve A, and similar parts thereof are similarly lettered.

It will be seen that the sleeve andspuppetvalve move in different directions to open the valve, so that the opening for the passage -of fluid is formed partly by the seat moving away from the valve, and partly by the valve moving away from the seat; and in this way the valve is fully opened `in half the time, or just twice as fast as an ordinary puppet valve could be opened.

The full opening of the valve is obtained almost instantly by very slight opposite movements of both sleeve and valve thus providing a large opening for the passage of the gas or iiuid, which can all pass practically-instantly and uniformly, instead of being gradually allowed to flow past with increasing rapidity and then gradually choked off with increasing rapidity. By thus increasing the rapidity of opening of the puppet-valve. more power can be obtained in the engine, owing to less back pressure; and more complete and instantaneous ignition is obtained.

The valve moves but about one-half the distance required to fully open it, and the seat moves the other half, the valve and seat moving oppositely and simultaneously when the shaft is turned, and both cams become operative.

In the construction illustrated the sleeve goes down and the puppet-valve goes up at the same time; and when they go as far as the cams permit the valve has opened as fully as an ordinaryvvalve would open with twice the extent of movement, and such an ordinary valve would require twice the time. Practically, if the. puppet-valves are the same diameter, the inlet valve A need not open as far as the outlet valve I3, and in such case the cams for operating the outlet valve maybe adapted to give a little more movement both to the valve and to its seat, at the opening of the valve so' that there will be a larger opening for the escape of the exploded gases, thus preventing back pressure in the cylinder.

In Figs. l, 2 and 3, the line 0 indicates the closedv position of the valves; the line that practically the explosive gases will flow instantly into the cylinder, and the exploded gases escape instantly from the cylinder; this if' a decided advantage as coinpared with the ordinary engines in which the valves open and close gradually and require approximately twice the time that my valves require for opening or closing; and

thereiore my valves can be made to stand fully open for at, least halt the time required for the opening and closing of an ordinary valve.

I have described and shown the valve and seat as moving uniformly in opposite, directions to or from each other but by changing the cams the relative extent in time ol' ymovement of the cam and seat can' be varied.

What I claim is: l. In a valve, the combination ot a seat,

and a valve simultaneously movable in opposite directions to open or close the valve; and springs for closing the valve.

2. In a valve, the combination of a sleeve having a seat in one end, a valve adapted to t said seat, a valve stem extending through the sleeve, means for simultaneously moving the valve and sleeve in opposite directions to open the valve; and a spring for closing the valve.

In a` valve, the combination of a reciprocatory sleeve having a valve seat, a reciprocatory puppet valve adapted to engage said seat, a spring for movingthe valve and sleeve in opposite directions to close the valve,` and means for moving the sleeve and valve in opposite directions to open the valve.

interposed between said collar and the sleeve to normally close the valve on the seat, and

means for moving the valveand sleeve in opposite directions to open the valve.

. 6. In a valve, the combination of a casing having a port, a sleeve communicating with l seni port an having e 'vai-ve seat, a valve ittinCr the said seat and havin e, stem eX- tending through the sleeve, a spring for ciosing the velve on .its seat, and means for simuitaneousiy moving the valve and seat in opposite directions to open the valve.

7. In combination7 e valve casing having a port, a sleeve communicating with said port having an open end provided with a valve seat, a. veive fitted to` said seat and eX- tending through the sleeve, :t coller on said stem, spring interoosed between said eolier and the sieeve, a sliiaft, cams on said shaft adapted to simultaneously move the sleeve and valve in opposite directions to open the valve.

8. In combination, a valve easing having e port, e sleeve communicating withl said port having an open end provided with a valve seat, e puppet valve fitted to said seat und extending through the closed end of the sieeve, a collar on said stem, a, spring interposed between said coilar and the end of the sleeve, e yoke attached to the end of eque es :en pam: my ne mined for the sleeve, a Cam ehaftfextenting through said yoke, cams on said shaftadepted to simultaneously engage the yoke and stem to move the sieeve and valve in opposite direstions, and e spring tor returning the sleeve to normal position.

9. n a valve, the combination of a. sleeve closed at one end., e Valve adapted to c'iose the open end of sani sieeve ami having e stem extending through the opposite end thereof, a leteial port in the wall lot saif sleeve, means for moving the valve heed away from seid sleeve and for simili` taneousy movingfsa-id sleeve in a direction opposite and away from the direction of movement of said heed. i

In testimony that I claimV the foregoing :is my own, I aix my signature in presence of two witnesses.
